I stayed 70 nights in June & Pop's apartment and I can truly recommend it!
Before my stay the communication with both of them was very easy (via. Facebook or What's app) and they answered all my questions within minutes.
The apartment itself was very clean, lovely decorated and very close to the BTS. It's also worth mentioning that the condo has a beautiful pool, a rooftop garden and a gym and that there're restaurants and street food stands as well as a 7/11 very close to it. (as far as I know there'll be a 7/11 in the lobby of the building very soon)
During my stay Pop supported me whenever I needed help and he also kindly offered to come by and help me clean the apartment every two weeks.
Overall I can say that I felt very comfortable and that the apartment became my home during my time in Bangkok!
